Apart from being inbred, their insanity comes from having to pray 5 times a day & each of those times must prostrate themselves a minimum 11 times each prayer session.
So do the maths – 5 x 11 = 55 times per day
7 x 55 = 385 times per week = 20,020 times per YEAR!
Just banging their heads on the ground for 10 years means these cretins have bashed their heads over 200,000 TIMES!!!
Anyone heard of punch drunk?
You’ll know a devout & crazy moslem by the bruise on their forehead!

@Firewing: Because people like Martin Luther King Jr. and Fred Rogers are religious. They were a reverend and a minister, in fact. The fact that some members of a group are dickbags does not demonstrate that the entire group is dickbags. It just means that the group is made of people, a demographic that contains a not insignificant amount of dickbags.

Besides, it's not like atheists never go after each other for, say, being too strident or not strident enough against religion as the speaker. Is atheism also "chaos, corrosion, destruction?"

Still, the choreography beats kneeling, which is pretty much every man for himself. And you have to admit that when a number of them slam their heads simultaneously it makes this really neat "Thunk" sound.
